Y suitable type-by which the operation of the.

press is regulated, the driving means being prises the rotation of thecylinder into the convenient position as above set forth.

For the accomplishment of my several objects, I have provided asemi-circular guard 21, such guard being in the form of an angle iron as15 best shown in Fig. 5. The lower ends of the curved guard 21 arepivotally mounted upon brackets 22 carried-by the framework 15, a spring23 being suitably connected to said guard and to the frame 15 forholding the guard normally moved to the limit of its motion to theright.

in'Fig. 3, in which position the guard embraces the heads of the screws19 as is shown in'Figs. 2 and 3. As will be readily appreelated, inorder to apply a wrench or other suitable tool to the heads of .thescrews 19 the guard member 21 must be moved towar in position upon anyone of the screws 19 in the uppermost half of the cylinder 17 since suchwrench' would hold the guard 21. out of normal position. In like manneran operator is prevented from starting the press while any one of thescrews 19 in the uppermost portion of the head 20 is in its inthe leftin Fig. 3 against the action of the spring 23.

In .order to utilize this movement of the,

uard is again upon the movement of the guard 21 out of normal positionan electric circuit shall be broken for rendering the press-driving Inthe construction shown, the switch comprises a block 25 of any suitableinsulating material secured upon'the arm 24,131,111 block 25 beingprovided, with a suitable contact member 26 normally held by means of asprin 27 spaeed a short distance above the b ock. The stationarymembersof the switch in the construction shown comprise contacts 28-29 whichare connected by any suitable means with the wires of a controllercircuit of any rendered inoperative, in the construction shown, by thebreaking of .the circuit through the. switch. As is best seen by aninspection of Fig. 3, when the guard 21 is swung to the left in thatfigure, the arm 24: is moved downward out of contact with a pin 30 whichserves normally as a stop for limiting the movement of the guard towardthe right. As the block 25 is moved downward, the contact member 26 iscarried downward therewith out of contact with the members 2829, servingthus to break the circuit through such members.

By the provision of the protecting means as above described, an operatoris prevented from starting the press while a wrench is' operativeretraetedfiaosition, since the guard 21 would be held out of normalposition by such projectin screw so as to cause the circuit through t eswitch members 28-29 to be held open.

In Figs. 6 to 10, inclusive, which show another form of construction,the parts which correspond to the parts above described are indicated bythe same reference characters, but with the addition of an ex ponent a.In the construction there shown, the screws 19, upon which the plateclamps 18 are adjustably mounted by means of screw-threads, arejournaled in heads 31 which are slidable longitudinally of the cylinder,said heads'being adjustable by means of eccentrics 32. A circular guard'33 is employed extending about the upper most head 31 and having an arm3% extending downward from its uppermost portion opposite the head 31.The guard is ivotally mounted upon the standard 15" y means of brackets35, being held normally at the limit of its movement in clockwisedirection in Fig. 10 by means 0'. a spring 36 connecting one of thebrackets 35 with the outwardly-extending arm 21. As will be readilyunderstood, the head 31 upon the uppermost portion of the cylindercannot be moved out of normal locking position by means of the eccentric32 with out first moving the guard 33 to the left in Fig. 10in order tohave access to the eccentric, such movement of the guard 33 serving toopen a switch such as that described in connection with Figs. 1 to 5,serving thus to render the press-driving means inoperative so long asthe guard is held out of normal position. It is clear that the guardcannot assume normal position until the head 31 and screws 19' have beenreturned to normal form-locking position, the press being thus renderedincapable of'opcration so long as the head 31, the screws 19 and theclamps 18 are held out ofplate-clamping position. It is also clear thatso long as an operating toolis kept in position for operating theeccentric, the press cannot be started, since such tool would serve toprevent the guard from assuming normal position.

In the preferred form. of mechanism as shown in Figs. 6 and 7, I providefor retaining the wrench 37 in position in the eccentric 32 during theentire form-locking and unlocking operation. As is shown in Fig. 8, theeccentric 32 is provided with a form cylinder, a screw adjustablelongirear,

slidable key 38 at one side adapted to be moved'inward to engage arecess 39 in the shank oi the tool 37 so as to hold the tool. againstWithdrawal or to be moved outward into engagement with a suitable recess40 in the head 31 so as to permit Withdrawal oi" the tool. By providingonly one recess 4:0 and that one located so as to receive the key 38only when the head is in form-clamping position, Withdrawal of the toolis permitted. only at that time, As is best shown in Fig. 9, the handles41-42 of the tool 3'? are preferably pivoted upon the shank of the tool,whereby such handles are adapted to be turned down out of the Way of theplate or other form being placed upon or taken from the cylinder so asnot to inter-- fore With the tree and easy manipulation of such plate.
